I use InDesign on an almost daily basis, and have done for many years trouble free. But today (of all days, with an impending publishing deadline), I get the "unable to verify your subscription" message. But this only happens with InDesign, as I've been using Photoshop and Acrobat without any probems today. I've recently updated to the new InDesign version, but it has been running problem free for a few days already. I seem to be going round in circles on the support pages. (Is it just me, or am I missing an obvious link? I just want to find a chat portal to type to a human being!) Any help would be much appreciated, thanks!
First, reboot your computer. That fixes many problems.
If the problem re-occurs, go to the upper right corner of the Creative Cloud desktop app (menu bar of Mac, task bar of Windows) where you see your avatar and Sign Out. Then Sign In again and try again in InDesign.
Thanks Steve, already tried the reboot (no success), so will try the sign out/in bit when I log on in the morning. InDesign is the only software that I've updated to the 2021 version of so far, so wondered if that was part of the issue too. Will update tomorrow morning...
